Ecosystem Chemistry Better Predicted By Plant Species
2013-04-09 09:49:55

Carnegie Institution Carnegie scientists have found that the plant species making up an ecosystem are better predictors of ecosystem chemistry than environmental conditions such as terrain, geology, or altitude. This is the first study using a new, high-resolution airborne, chemical-detecting instrument to map multiple ecosystem chemicals. The result, published in the April 8, 2013, Early Edition of the Proceedings of the National Academy of Sciences, is a key step toward understanding how...

Plant Biodiversity Protects Ecosystems From Human Perils
2013-02-07 08:59:14

April Flowers for redOrbit.com - Your Universe Online A new study led by integrative biologists at the University of Guelph warns of the perils inherent in an ecosystem breakdown. The findings of the study, which appeared as the cover story in today´s issue of the journal Nature, suggest that resource managers and farmers should not rely on single crop monocultures, no matter how stable they may appear to be. The team suggests instead that farmers should cultivate the growth of more...

There Is A Limit For How Long Plants Can Adapt To Drought
2013-01-23 13:50:15

University of Arizona Plants can adapt their demand for water depending on how much is available - However, this resilience has a limit, and prolonged drought conditions threaten the survival of plant communities, especially in more arid areas Scientists with the U.S. Department of Agriculture, or USDA, and their partners have determined that water demand by many plant communities can fluctuate in response to water availability, indicating a capacity for resilience even when changing...

Extreme Weather Events May Synchronize Entire Communities Of Species
2013-01-18 04:26:31

April Flowers for redOrbit.com - Your Universe Online Scientists have known that climate change affects the population dynamics of single species, such as reindeer or caribou, but the effects of such climate change at the community level have been much harder to document and quantify. A new study from the Norwegian University of Science and Technology (NTNU) has found that extreme climate events cause a synchronized population fluctuation among all vertebrate species in a relatively...

Biologists Dig In The Dirt For Soil Microbes
2013-01-03 18:59:36

Brett Smith for redOrbit.com — Your Universe Online Understanding biological diversity has been the key to learning how ecosystems around the world function in a sustainable manner. A team of American and Australian scientists has taken this philosophy and applied it to a section of the ecosystem that has largely been ignored, the microbial communities that lie just below our feet. “We´ve been walking around on soil since the beginning of time and never really knew...

Provides scientists and policymakers with insights for selecting and managing conservation areas How can a square meter of meadow contain tens of species of plants? And what factors determine the number of species that live in an ecosystem? Science journal has defined this as one of the 25 most important unresolved questions in science, both for its importance in understanding nature and due to the value of natural ecosystems for mankind. The value of goods and services provided by natural...

Climate Change Is Having Major Impact On Biodiversity
2012-12-20 14:38:33

redOrbit Staff & Wire Reports - Your Universe Online Global warming is causing plant and animal species to alter their geographic ranges and the timing of key life events such as migrating, flowering, or laying eggs -- a shift that could adversely impact biodiversity as well as ecosystems, a new government report has revealed. The range and timing-related changes are occurring faster now that they were just a few years ago, report the authors of "Impacts of Climate Change on...

Great Lakes Study Highlights Environmental Threats And Challenges
2012-12-18 09:46:53

April Flowers for redOrbit.com - Your Universe Online A research team, led by the University of Michigan, has developed a comprehensive map telling the story of human impact on the Great Lakes and identifying how "environmental stressors" stretching from Minnesota to Ontario are shaping the future of an ecosystem that contains 20 percent of the world's fresh water. The map, three years in the making, was a collaborative effort with the University of Wisconsin-Madison and a binational team...

While science has often focused on big-scale, global climate change research, a study recently released in the journal Bioscience suggests that long-term, integrated and site-specific research is needed to understand how climate change affects multiple components of ecosystem structure and function, sometimes in surprising ways. “Long-term ecological research is important to understanding the effects of a changing climate on our natural resources and so much more,” said Michael...
